Irving collapsed to the floor on a drive to the basket in overtime and immediately clutched his knee, the same knee that has been causing him troubles with tendinitis for over a month.

While he initially returned to the bench with the possibility of returning to the game, he was seen walking back to the locker room early and in visible pain as he threw his jersey to the ground in frustration down the tunnel.

Initial tests done by the Cavaliers medical staff revealed that there was no serious damage to either his ACL or MCL, but the player himself insisted that this injury felt different to those that have bothered him in the past.

“You can hear in the tone of my voice that I’m a little worried,” Irving said, ESPN reported.

“I just want to make sure everything is OK, and I’m going to take the necessary steps to see what’s going on.”

Irving had played well during his time on the court, putting up 23 points, seven rebounds and six assists as well as four steals as he came up with a crucial stop on Stephen Curry at the end of regulation to help force the game to overtime.

However, the Cavs now face an anxious wait for news on how bad his setback is and it is unclear as to whether or not he will be in contention to play in Game 2 in Oakland on Sunday night.

Warriors coach Steve Kerr insisted that it is something that he “hates to see” and hopes the Cavs point guard can make a recovery for the rest of the series.

Golden State lead 1-0 after winning Game 1 108-100 on Thursday night, and having already lost Kevin Love, it will take a special effort from the Cavs to stay in the series if Irving is ruled out too.
